Once again, if something like 0w30 or 5w30 works well during winter, and the manufacturer does not require you to run anything thicker, then why bother switching to something thicker for summer?

There is no direct advantage, but if the 0W was achieved through the use of more VIIs, then all else being equal, the 5W or 10W would be a more durable oil.

The manufacturer doesn't necessarily spec the best oil for each condition. Thet limit choices to keep things simple. There is a lot of compromises and their priorities frequently aren't the same as the owners priorities.

That said, I personally still wouldn't mess with different oils for different seasons unless maybe if I lived in East Snowshoe Montana.

I find the manufacturers specs to be "good enough" but am not naive enough to believe the manufactures viscosity specs are optimum for each operating condition.

No, 5w30 is a viscosity grade. A spec(ification) would be something like ACEA A3, or API SM, or some other set of criteria.

I'm not sure you understand that SAE "spec"ifies a visc range and that the 504 oils VW "specs" is indeed 5w30. Are you rather trying to make a point about syntax? It's not really clear from your post.


No, I'm trying to make - or rather, I assumed someone as pompously "knowledgeable" as you would infer - the point that an SAE viscosity is not the same as a "specification."

I don't think you understand as well that 0w30 GC and 0w-40 M1 DO NOT "provide the best possible starting".

Some references would help the group understand your backwards assertions.


Show me a 5W-XX that is less viscous at any realistic starting temperature (e.g., 15F-90F) than the two oils, or any 0W-XX for that matter, that I mentioned, Professor.

Quote:
Maybe it was my fault you missed it, but I clearly indicated, as is common knowledge, that VW services are done with 5w-40 oil, which I consider thick..especially bearing in mind that 5w30 is speced in Europe. Are you saying I should not use their oil, that I should BYO oil or what?


Aren't you the same one who argues all the time with the VW techs over on Vortex about how it's fine, or even "better" sometimes, to use non-spec or non-dealer oils? You really need to make up your mind.

I don't see any information in that chart you posted about 0W-XX oils, nor do I see anything there - or in the rest of your non-sensical response - explaining the advantage of running a "thicker" oil in the summer.

It's not that your posts are complicated. It's that they contain nothing resembling a coherent answer.

Here, I'll put it in crayon for you since you asked:

Why doo U yoose hEavier Oilz in da summer wen der is no reezon to du that?

Ok, now run them both for 80F starts and see which one is lubing your engine faster in the summer at startup. And explain what the advantage would be to using the Mobil 1 Turbo Diesel Truck in the summer.

Oh, so now we refer to figures from the manufacturers? You didn't see to think too highly of those a couple months ago on another forum:

You can read and compare Product Data Sheets all day, but it'll give little insight as to how an oil will perform in-service. Oils with the lowest this or highest that does not translate to lowest wear or best TBN retention.

Is that a good reference?

Not any more. He got banned.

It was the same here. Used to hold a light on AE Hass because he runs 0w-20 in a Ferarri, yet doesn't do it with his own cars. (Not Ferarris, but still....) To say nothing of the nonsense given to those who use mfg spec oil...

Case in point. http://www.bobistheoilguy.com/forums/ubb...063#Post1470063

Wow, this thread has turned into a regular clown party.

I guess the concept of thin oil in winter and thick oil in summer is too complicated for the group. You guys don't even understand the basic properties of the oils involved. Why don't you guys tell me at what temp Mobil 1 0w-40 is thinner than my 5w30...please, I'm dying to know. It's freakin hilarious all you guys want to do is post, without thinking or doing your homework.

By "posting" I mean looking for strands in your head that you think proves I'm wrong about something...lol, like comparing oils by their PDS: The ONLY thing you can compare from PDS is visc...lol, but that contradicts me? No, because I'm *talking about visc*.

Funny how me saying my engine "specs" 5w30 in Europe and 5w-40 in USA is a nit-picking problem for you. lol, that's all you have...terminology? It happens to be 100% accurate and anyone else here knows EXACTLY what it means, except the chorusline of crybabies on this thread.

Come on, show me wrong! Show me how 0w-40 is thinner than 5w30, show me how only speced oils work properly, even though the data shows otherwise. Show me you are men who know what you are talking about before you criticize someone else...because I don't think you know what you are talking about.


lol, unreal.


VWVortex? There's a nucleus of deep thought.

A lot of snotty words. Still no answers.

This is my "surprised" face.

 

[pbm]

I thought I'd join this 'clown party' just to say that I too have used thicker oil in summer and thinner oil in winter. I use 10w30 oil in my Buick which specs 5w30. I have used 10w30 in the summer in my Accord which specs 5w20. The main reason I do this is because I have the 10w30 (usually from sales) and summer is the time to use it up.
I'm not saying it protects better than the 'recommended' grade but I haven't noticed any negatives either.
In all fairness to AJ, he does state that he uses the thicker oil because it is a FREE dealer oil change.


PS: I do think that Mobil 1 5w30 is thinner at 0* to 32* F than GC 0w30? Am I correct?

So you have nothing? You should have just said so.

At least one member has the power of reading comprehension. Thanks.

 

[BobFout]

If we compare a correct 5w30 (504.00 would be used in the 2.0T, not ACEA A5) to Mobil 1 0w40, Mobil 1 0w40 is thinner at all temps below 20C.

Yes, GC is Mid-HTHS Euro oil, Mobil 1 5w30 is a lower-HTHS API oil.

 

[GMorg]

Perhaps someone would run thicker oil in the summer because it isn't too thick and it is FREE. But, they would be willing to pay for oil that is thinner during the cold start-up months in PA. Perhaps if Mobil 1 0W40 was free, then AJ would not switch back and forth and perhaps if 5W30 was free, again AJ would not switch back and forth. However, we may never know.

 

[Trajan]

Well, living in PA, I haven't ever seen any reason to switch between 0w and 5w.

I run a 0w in July, I'm running a 0w now.

 

[d00df00d]

I'd be happy running a 0w-30, 0w-40, 5w30, or 5w-40 year-round (although I'd prefer the thinner grades). The only reason I'm running a 5w-40 now is that that happens to be the viscosity of the formulation I want. If I could get the same goods from one of the other grades, I'd run one of them in a heartbeat.

 

[GMorg]

I don't see the complexity here. It seems AJ also would prefer the thinner grades at start-up, but is willing to tolerate 5W40 during the summer because it is FREE for him. It seems that most of participants in this thread have a similar position and yet are arguing about it.

If you read his responses to other threads on similar subjects in the past, you will see that he advocates the use of thicker oils during summer and thinner oils during winter, regardless if it's free or not.

For me, this simply makes no sense, not to mention that it's impractical since I only do one oil change a year typically.
